You have the right of ownership (4)
I believe the answer is:
your
'ownership' is the definition.
(I've seen this before)
'you have the right' is the wordplay.
'have' is a charade indicator (letters next to each other).
'the right' becomes 'r' (common abbreviation).
'you'+'r'='YOUR'
'of' is the link.
(Other definitions for your that I've seen before include "Thy" , "See 12" , "Second person's" , "See 14" , "-- Majesty; -- Grace" .)
